Anti Ram-Raid Protection
CIS Street Furniture have supplied their unique ram raid bollard system, type 194RR, to several military bases across the UK.
When not in use this unique anti ram bollard sits in a box set below ground level. With a simple lift and drop movement the bollard is locked in a vertical position providing full anti ram resistance and giving the ultimate in security.
CIS Street Furniture also offer a wide range of fixed cast iron anti ram bollards by strengthening the cast iron with the addition of a steel core to the inner section of the bollard. Steel and composite bollards can also be formed into anti ram by using a 10mm thick wall to provide ram raid control. At 10mm wall thickness the bollard will absorb a 30 tonne spot impact (subject to suitable foundation details). This give a range of styles available to suit the scheme’s design brief.
Also available are a range of telescopic bollards that are most inconspicuous, hidden below ground level. When extended, a high security key operation locks the bollard in the upright position to give outright ram raid control.

Full System (199)
A steel core is added to a bollard as above. Also supplied is a below ground metal casing. The bollard is set in the casing and packed with pea gravel. The top quarter is concreted as normal. The impact of a motor vehicle will be absorbed such that the bollard will deflect to an angle of approx. 40 degrees to the ground. This should render the vehicle immobile.
Core only (199x)
A steel core is bonded to the inside of the bollard with sand and cement. This extends the bollard root to approx. 500mm. This should then be fixed to a suitable foundation.

Anti ram-raid bollard installation
Care is required when designing suitable foundations for this type of bollard. We would always recommend consulting a local qualified Structural Engineer.
For anti-ram raid, core only bollards, concrete foundations should be a minimum of 4 x diameter of the bollard and 2 x the root length of the bollard. If in any doubt always check with your Structural Engineer.
